Title: Device for monitoring a friction clutch, more particularly on a motor vehicle
Inventor: NAGLER FRANZ
IPC: F16D48/02
Filed: 1987-01-16
Abstract: In order to monitor the power dissipated by friction and wear on friction linings, in a motor vehicle clutch, the instantaneous power PI dissipated by friction is calculated from the instantaneous couple M(s, t) transmitted by the clutch and the difference between the input speed omega m (t) and the output speed omega g (t) of the clutch, a mean value PI, of this power being determined by integration. The mean values thus obtained during successive actuations of the clutch are summed and, after correction to take account of cooling, the cumulative value P's is compared with a maximum allowable value Pmax. If this maximum value is exceeded, a light signals the thermal overload on the clutch. Monitoring of the slipping of the clutch, under conditions of thermal overload, is furthermore capitalised on in order to indicate excessive wear of the friction linings.
